AIR BAG MODULE COVER STRUCTURE Abstract Tear lines as brittle portions are provided not in the surface of a module cover (22) liable to influences of external factors such as rain, dust, etc. but at upper portions of three side s surfaces other than the side surface facing to the vehicle front side, of four side surfaces of a roughly rectangular parallelopiped-shaped air bag module (20). Three tear lines are provided; specifically, both side surfaces facing in the vehicle width direction are each provided with a first tear line (26) at portion (B) shown in the figure, and a second tear line (27) is provided in portion (C) shown in the figure other than portions (D) shown in 1o the figure as slits (4) for passing air bag support belts therethrough. Therefore, at the time of inflation and development of the air bag, the module cover (22) is developed in such a manner as to open a lid, with one side on the vehicle front side of a casing (23) as an axis. Besides, at one side on the vehicle front side, stoppers are formed to make it difficult for the module cover (22) to be opened beyond a predetermined angle. C)C coo c1r |
